Wav to Base64 converter in CFD

[idkhtn]

Hello,

In my CFD app I'm trying to write a custom c# script Base64 converter in order to convert wav output from Record component (Record1.AudioId) to a base64 string (put to variable OutputText) that could be later embedded in JSON request. What is the correct approach here?

Any help appreciated!

The AudioId is the file path. So you will need to read the file contents, encode it as you need, and return the encoded text.

Thank you for quick answer My solution so far consists of:

My input parameters:
AudioId String Record1.AudioId


1.reading the contents of the audio file and assigning it to "bytes" Variable (should I also add "bytes" to input parameters? )

byte[] bytes = File.ReadAllBytes(AudioId);

2.encoding using ToBase64String
string base64 = Convert.ToBase64String(bytes);

3.assigning the returned value to OutputText using assign variable component (should I do it inside the script?)

im also getting an error that not all code paths return value

:[33168..33192)E: (627,27)-(627,51): Error CS0161: "Main.ExecuteCSharpCode11743652179ECCComponent.ConvertWavToBase64String(string)": Nicht alle Codepfade geben einen Wert zurück. private object ConvertWavToBase64String(string AudioId)
^^^^^^^^^^^^^^^^^^^^^^^^

byte[] bytes = File.ReadAllBytes(AudioId);
string base64 = Convert.ToBase64String(bytes);
return base64;

Now the error seems to be resolved
